Struct UnknownValue 

pub struct UnknownValue {
    pub value: String,
    pub expected: String,
}

A string that is not one of a closed vocabulary’s values.

Carries what was read and what was expected, because the two together are what a caller needs to correct a stored value or a request field.

Fields

value: String

expected: String

impl Eq for UnknownValue

impl Error for UnknownValue

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
